Abstract
Description
TABLE 1 ______________________________________ Baseband Video The standard composite video signal comprising all video information, synchronizing pulses, and audio information. It spans the frequency range of 0 to 6 MHz. Cable TV signal Covers the frequency range of approximately 54 to 552 MHz. F connector The standard 75 ohm coax connector used in homes and businesses to interconnect video and RF signals. The center conductor is the physical center conductor wire of the coax cable, and the shell is threaded. Head-End The central location where the cable TV signal is assembled, amplified, and distributed from the cable TV operator to the customer. NAB National Association of Broadcasters NTSC National Television Standards Committee, the committee that governs the color system compatible with black-and-white television. SCTE Society of Cable and Telecommunications Engineers SMPTE Society of Motion Picture and Television Engineers Sub-split Refers to the return signal from the customer to the head-end. The customer set-top boxes are not available to provide this signal yet, but the cable TV companies have either installed or are in the process of installing onto the cable system the equipment required to handle this signal. Sub-split signal Covers a relatively small frequency range but a band from 5 MHz to 50 MHz (or up to 200 MHz for some requirements) has been set aside for this return signal (from the customer to the head-end). ______________________________________
